Q.10 A worker pushes an object of 20 kg down on a rough inclined plane with a force F as shown mass m = 20 in the figure. The incline makes an angle 0 = 30° with the horizontal. This object accelerates 4.91 m/s² . Take g = 10 m/s² . Knowing that the force of kinetic friction is fr = 58.11 N, determine the magnitude of the applied force. at a rate a = %3D mg %3| (a) F = 45 N (b) F = 59.9 N (c) F = 102.3 N (d) F = 8.9 N %3D %3D %3D
